Analysis of factors influencing telephone call response rate in an epidemiological study. ScientificWorldJournal; 2014:1793752356-6140http://hdl.handle.net/10668/2075Descriptive epidemiology research involves collecting data from large numbers of subjects. Obtaining these data requires approaches designed to achieve maximum participation or response rates among respondents possessing the desired information. We analyze participation and response rates in a population-based epidemiological study though a telephone survey and identify factors implicated in consenting to participate. Rates found exceeded those reported in the literature and they were higher for afternoon calls than for morning calls. Women and subjects older than 40 years were the most likely to answer the telephone. The study identified geographical differences, with higher RRs in districts in southern Spain that are not considered urbanized. This information may be helpful for designing more efficient community epidemiology projects.enRecolección de datosEstudios epidemiológicosFemeninoTelefónoMedical Subject Headings::Analytical, Diagnostic and Therapeutic Techniques and Equipment::Investigative Techniques::Epidemiologic Methods::Data CollectionMedical Subject Headings::Analytical, Diagnostic and Therapeutic Techniques and Equipment::Investigative Techniques::Epidemiologic Methods::Epidemiologic Study Characteristics as Topic::Epidemiologic StudiesMedical Subject Headings::Check Tags::FemaleMedical Subject Headings::Information Science::Information Science::Communications Media::Telecommunications::Telephoneresearch article25401127open access10.1155/2014/1793751537-744XPMC4221860
